Benefits of technology

This patent describes a gear arrangement that allows for misalignment between the input and output, while still maintaining meshing engagement between the gears. This arrangement features male and female gears, with the female gear being supported on the male gear by spherical bearings. The joint between the hub and shaft allows for lateral articulation of the roller gear with respect to the shaft, ensuring transmission of drive from the power system to the roller gear throughout the range of angular movement. The technical effects of this invention include improved flexibility and adaptability for gear arrangements in various applications, such as industrial and agricultural equipment.

Problems solved by technology

However, a drive system onboard an aircraft would likely be confronted with challenges arising from loadings and wheel deflection imposed upon landing gear during take-off and landing of the aircraft, particularly at times when the landing wheel moves into and out of contact with the ground surface.

Embodiment Construction

[0056]The embodiment is directed to a drive system 10 for an aircraft, operable for selectively enabling ground movement, and in particular taxiing movement, of the aircraft without requiring the aircraft to be moved by a ground vehicle.

[0057]The drive system 10 is selectively operable to impart rotational drive to landing gear 13 of the aircraft. Referring in particular to FIGS. 1, 2 and 3, the drive system 10 delivers rotation and torque to a landing wheel 15 forming part of the aircraft landing gear 13. The landing wheel 15 includes a wheel rim 17 onto which a tyre is fitted. Only the rim 17 of the landing wheel 15 is shown in the drawings. In the arrangement shown, there is a single landing wheel 15, however the arrangement can be configured to drive aircraft landing gear having dual landing wheels, as would be understood by a person skilled in the art.

[0058]The drive system 10 comprises means 20 drivingly coupled to the wheel rim 17 to receive rotation and torque, and to transm...

Abstract

A drive system (10) for an aircraft, operable for selectively enabling ground movement, and in particular taxiing movement, of the aircraft without requiring the aircraft to be moved by a ground vehicle. The drive system (10) comprises a power system (25) and a mechanical transmission (23) for delivering rotational drive to landing gear (13) of the aircraft. The mechanical transmission (23) comprises an input (41) for receiving drive from the power system (25), an output (43) for delivering drive to the landing gear (13), and a gear mechanism (45) operably coupling the input and output to transmit drive from the input to the output. The gear mechanism (45) is configured to accommodate some misalignment between the input (41) and output (43).

Description

TECHNICAL FIELD[0001]This invention relates to a mechanical transmission for transmission of mechanical power between an input to an output.[0002]This invention also relates to ground movement of an aircraft, for which it has been devised particularly. In this respect, the invention is concerned with ground movements of aircraft using propulsion derived from the aircraft and delivered by way of a mechanical transmission.BACKGROUND ART[0003]The following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.[0004]The invention has been devised particularly, although not necessarily solely, in relation to ground movements of aircraft using propulsion derived from the aircraft and delivered by way of a mechanical transmission. Accordingly, the following di...
